Inventory & Asset Management

"Inventory" means different things: a warehouse's SKU + stock, an electronics lab's parts bin, an IT department's laptop fleet. This page covers all three. For ERP-grade inventory inside a wider system see ERP Systems.

Warehouse / stock (multi-location, SKUs, sales-linked)

• ★ ERPNext Stock — full WMS-lite inside ERPNext: bins, batches / serial numbers, transfers, BOMs, reorder rules. GPLv3. The default OSS pick if you'll grow beyond a single warehouse.
• ★ Odoo Inventory — extremely capable; barcode flows, putaway / removal strategies; Community Edition is free, advanced routing in Enterprise.
• OpenBoxes — open source; humanitarian-supply-chain origin; warehouse + lots / batches / FEFO.
• Tryton Inventory — modular; clean.
• Dolibarr Stock — basic but workable.
• inFlow Inventory — paid SaaS; small free trial.
• Zoho Inventory Free — genuine free tier (up to 50 orders / month).
• Sortly — modern small-business inventory; free tier.

Manufacturing / BOM-flavored

• ★ ERPNext Manufacturing — work orders, BOMs, routing, capacity planning; free with ERPNext.
• Odoo Manufacturing — strong; many modules in Enterprise.
• MRPeasy, Katana — paid SaaS aimed at small manufacturers.
• FlowMRP — newer OSS-flavored MRP.

Electronics / parts bin

• ★ PartKeepr — venerable; AGPLv3; component database with footprints / datasheets / parametric search. Best for an electronics lab / hardware shop.
• ★ InvenTree — modern OSS inventory + parts management; Python; MIT. Default in 2026 for "I have parts in bins and want to know what I have."
• partsbox.com — hosted; generous free tier; popular with hobbyists.
• Bitlocker / Boxes / KiCad BOM tools — for project-level BOM, not warehouse stock.

IT asset tracking

• ★ Snipe-IT — open source IT asset tracker; AGPLv3 (or commercial license); checkouts, depreciation, license keys, maintenance schedules. The default OSS pick.
• ★ GLPI — IT asset + helpdesk + ITSM; long-running OSS. See Helpdesk & Ticketing.
